Safety Data Sheet
Getting an SDS for Imazapyr
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Imazapyr issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
04 · Precautionary statements
Imazapyr precautionary statements
CLP Annex VI assigns 8 precautionary statements to Imazapyr. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
Imazapyr name in 23 EU languages
CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

Imazapyr health hazards and exposure limits
Imazapyr hazard summary
The imidazolinones are not reproductive or developmental toxins and lack genotoxic and carcinogenic potential; They are relatively nontoxic in acute toxicity testing; [Krieger, p. 1853-63] An eye irritant; [MSDSonline] See Imazapyr isopropylamine salt.

Imazapyr carcinogenicity classification
Cancer Classification: Group E Evidence of Non-carcinogenicity for Humans
Source: Hazardous Substances Data Bank (HSDB)
An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.
